Pt a creste performantele motoarelor se gasesc in comert o gramada de produse care maresc cantitatea de aer care intra in motor: filtre de aer sport, turbosuflante, prize de aer, etc... Conform statisticilor, cu un simplu filtru de aer aproape ca dublezi cantitatea de aer care intra in motor, daca il mai conectezi si la o priza de aer si pui o turbosuflanta mai puternica (sau pui un chiptuning care mareste rotatia turbosuflantei) atunci o sa ai o cantitate tripla sau chiar mai mult aer care intra in motor. E la mintea cocosului ca pt o combustie sanatoasa ai nevoie de oxigen (de aceea e binevenita o priza de aer prin care se introduce aer rece, care e mai bogat in oxigen)... Ceea ce nu inteleg eu, si aici poate ca gresesc deci va rog sa ma corectati, daca bagam o cantitate tripla de aer dar acelasi volum de combustibil... cum vom obtine performante mai mari ? Pana la urma oxigenul nu arde, el doar intretine arderea... In cazul chiptuning-ului din cate stiu se mareste si cantitatea de combustibil care intra in motor prin prelungirea timpului de injectie, dar presupunand ca nu am marit cantitatea de combustibil ci doar cantitatea de aer... vom obtine performante mai bune ? Si asta chiar nu e intrebare retorica... sunt chiar curios ce se intampla... ma gandesc ca poate datorita cantitatii marite de oxigen arderile ar putea fi mai violente, de aici rezultand performante mai bune... habar n-am... |

Este un fel de boost manual care se instaleaza la motor. Mai jos se afla explcatia, este in engleza dar nu cred ca este o problema, noi romanii suntem poligloti din nastere
The "Boost Enhancer" is a simple yet precise and well thought out adjustable boost pressure relief valve. The "Boost Enhancer" brings on the boost in the Porsche 951 (944 Turbo) earlier. Much earlier. CAD designed and CNC machined from 6061 Aircraft Grade Aluminum with a red and blue anodized finish. The Nylon Poppet with Nitrile Rubber Seal rides in a cylinder style bore maintaining a perfect re-seal every time the boost comes back down. With a full 1/4" bore for maximum signal flow to wastegate when needed. This device completely prohibits airflow to the wastegate until you want it. Fully adjustable 0 to 20 PSI and factory set at 10. This allows you to fine tune for your particular engines requirements. By completely closing the flow of pressure to the wastegate diaphragm and keeping it closed, it eliminates losing valuable exhaust gas pressure prematurely and spools the turbo up quicker. Then at the appropriate pressure setting, opens, and allows the wastegate to function normally and monitor the maximum boost pressure. This translates into quicker boost and more horsepower from the lower RPM range. If you didn't care about looks, you wouldn't own a Porsche. The Boost Enhancer is the best looking of the boost devices as well. Completely unique and professional to match its unique inner workings. -------------------- Porsche 944 turbo S2, 2.5L, 370hp
